Recently had pool guy install a Hayward Aquarite 940. About 3 weeks ago.
My pool is approximately 20k gallons.
Things seemed to be going great. We run our pump 24 hrs, and with the SWG set at 50p the FCL built to close to 5ppm. We started turning it down to 40p, then 35p, then 30p. We stabilized to around 1.7 ppm. Probably a little low, but that’s where it was.
About a week later, the FCL is at 0.5ppm I figure, I got too aggressive with going low, so I put it back to 50p. The FCL never budged. 0.5ppm for a week. CCL stayed between 0.0 - 0.2. I contacted the pool guy, he said to put in Super Chlorinate. After 24hrs, we were up to 0.9ppm. Power cycled to clear the memory, ran Super Chlorinate again for 24hrs. FCL up to 1.8ppm. Repeat. FCL up to 3.0ppm. He wanted me to get to 3.0ppm. Seemed reasonable.
Turned it back down. Sunny day. A good amount of swimmers. Didn’t check it before bed. Pump ran all night. This morning FCL is 0.5ppm. I ask pool guy and he thinks it could be a high chlorine demand. Sunny day. Heavy use. Turn on super chlorinate, put a cup in front of a jet, test that water. I test it and it’s at 2.0ppm the water in the deep is 0.5ppm. (I can’t crack a union and test there because I have a broken arm - so the 2.0ppm isn’t crazy accurate, but it’s higher than existing so the salt cell is working somewhat). Seems like it should be much higher.
I’m just not sure what to think. It seems like my salt system isn’t generating enough chlorine. To keep it at 3.0ppm, I’d have to run it at 100p constantly. My pool guy, is a great guy. Very practical and seems honest. I believe we have a 3 year warranty on the unit, but he obviously wants to check everything first before we go that route.
Mind you, my water is crystal clear. Doesn’t smell. Feels nice. All in all, you’d think I’d be happy. PH may be a tiny bit high, but that’s to be expected with running in super chlorinate for a few days. Maybe I’m just testing it and worrying about it too much. I just don’t want to wake up to an algae bloom at some point.
Also, I should add that I have never shocked the pool since we opened it back in April. The CC has never been above 0.3. We just bought the house, the pool was green and black. I read on the forums and the site how to maintain a pool and it has been great so far. We wanted to switch to SWG for the water feel and no CYA issues.
I appreciate any thoughts, suggestions and comments.
My tests this morning:
AquaRite 940
Vinyl pool
Approx 20,000 gallons
Using LaMotte ColorQ 7
FCL 0.5
CCL 0.1
PH 7.7
ALK 78
CH 150
CYA 70
SALT 3200 (on panel of AquaRite and verified myself with a salt test)
Phosphate 700 (from pool store, I just had them test because I was in the area And wanted a double check)
Total Dissolved Solids 3700
